Selecting the Script File

Class ScriptDrivenAccountSuite contains two private instance variables:

• scriptFileName -- the path name of the script file containing the test commands to execute
• account -- the current Account instance, created for the most recent newAccount command, on which the deposit, withdraw, and getBalance commands will operate.

Here are ScriptDrivenAccountSuite's instance variables:

public class ScriptDrivenAccountSuite extends Suite {

    private static String DEFAULT_SCRIPT_FILE = "script.txt";
    private static String scriptFileName;

    private Account account = new Account();

ScriptDrivenAccountSuite's no-arg constructor sets the scriptFileName to the value of the system property ScriptFile. If ScriptFile is not set, the constructor initializes scriptFileName to its default: "script.txt".

Here's ScriptDrivenAccountSuite's no-arg constructor:

    /**
     * Construct a new <code>ScriptDrivenAccountSuite</code>. If
     * the <code>ScriptFile</code> system property is set, the
     * value of that property will be used as the script file
     * name. Else, <code>script.txt</code> will be used.
     */
    public ScriptDrivenAccountSuite() {
        scriptFileName = System.getProperty("ScriptFile");
        if (scriptFileName == null) {

            scriptFileName = DEFAULT_SCRIPT_FILE;
        }
    }
